Heating Up the HVAC Industry: Closing the Gaps in Mentorship, Training, and Trust with Joshua Griffin

A rapidly changing HVAC industry is being shaped by refrigerant shortages, a deepening labor gap, and shifting expectations from homeowners. With refrigerant regulations evolving and long-trusted standards like R410A being phased out, contractors and technicians are navigating not only technical complexity, but also a growing need to rebuild trust and transparency with customers. The compressed timeline for adopting newer A2L refrigerants like R454B has created confusion and bottlenecks across supply chains, leaving many professionals scrambling for clarity and consistency.

With accelerated refrigerant phase-outs, supply disruptions, and profit-driven practices reshaping the landscape, how do homeowners know whom to trust—and how should technicians adapt to stay both ethical and profitable?

In this episode of Straight Outta Crumpton, host Greg Crumpton is joined by Joshua Griffin, founder of the New HVAC Guide and host of HVAC Guide for Homeowners. Together, they dive into what’s really happening inside the HVAC industry—from refrigerant controversies to the ethics of commission-based sales—and explore how education, transparency, and “growth groups” can reshape the trade’s future.

• Homeowners vs. Sales Tactics: Griffin critiques commission-based sales models in residential HVAC, arguing that they incentivize replacements over repairs—often to the homeowner’s detriment.
• The R454B Controversy: Griffin and Crumpton tackle the refrigerant shortage head-on, claiming the transition to A2L refrigerants like R454B has been forced without proper planning, resulting in inflated prices and limited availability.
• A Call to Mentorship: The pair discusses the urgent need to pass on hands-on wisdom through growth groups and mentorship, with Griffin inviting veteran techs to contribute to his educational platform for homeowners.
